DUPLEX FASTENER-SETTIN G MACHINE.

Specification of Letters Patent.

Patented Jan. 21, 1919.

Application filed July 21, 1915. Serial No. 41,178.

To all whom it may concern Be it known that I, GEORGE GoooU, a citizen of the United States, residing at Winchester, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Duplex Fastener-Setting Machines, of which the following description, in connection With the accompanying drawings, is a specification, like reference charactors on the drawings indicating like parts .in the several figures.

This invention relates to du lex machines for simultaneously inserting asteners, such as lacing hooks or eyelets, in the edges of two pieces of work or of a folded piece of work.

"Duplex machines as heretofore constructed are arranged to receive work presented with the edges in which the fasteners are to be set substantially opposite to each other, and the corresponding fasteners are set in axial alinement with each other. Under these conditions one portion of the Work obscures the other portion so that it is difficult for the operator to ascertain whether or not the fasteners are being supplied and properly inserted in the concealed portion of the work before the work is removed from the machine. One object of the present invention is to provide a machine organized to set fasteners simultaneously in two edges of work presented with one edge extending beyond the other. When so presented the fasteners inserted in bothedges will be open to the View of the operator-as they are inserted. An important feature of the invention, accordingly, consists in a duplex machine having opposed pairs of fastener setting dies, one or more of which pairs are located out of alinement with the corresponding pair or pairs.

WVhile the invention is herein disclosed as embodied in a machine for setting two fasteners at a time, one in each edge of the work, the invention could be embodied with good advantage in a machine of the gang type in which two or more fasteners are set simultaneously in both edges of the work.

The invention is herein illustrated as em bodied in a duplex hook setting machine designed to set lacing hooks in the uppers of boots and in this operation the upper is folded in a non-symmetrical manner; that is to say, with the edge of one quarter opposite to the body portion of the other quarter. That quarter of the upper which is farthest from the eyes of the operator projects be yond the edge of the other quarter and where the work is handled in an inclined position the lowermost quarter will project beyond the edge of the uppermost quarter. Consequently the clenched ends of the hook barrels will be visible upon the inside of the lowermost quarter and the heads of the hooks will be visible upon the outside of the uppermost quarter as soon as the work has been fed past the setting instrumentalities.

Another feature of the invention consists in feeding means arranged to engage and feed the two sides of a non-symmetrically folded upper or the like in an intermittent manner. As herein shown the feeding members are pivotally mounted and the shorter member has imparted to it the greater angular movement in order that the linear feeding movement of both sides shall be equal.

The features above discussed and others inoldent to the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which Figure 1 is a view in side elevation showing the operating parts of the machine;

Fig. 2 is a View in perspective of the setting instrumentalities and their associated parts;

Fig. 3 is a plan View partly in section showing the position of a shoe upper in the machine, and

Fig. 1 is a sectional view of the upsetting die holders and associated parts.

In one of its aspects the invention consists in improvements in the machine disclosed in Letters Patent of the United States No. 1,217,088, granted February 20, 1917, on my prior application, and in the accompanying drawings only so much of that machine is illustrated as is necessary for a complete understanding of the present invention.

The machine frame 2 is provided with journals for a cam shaft 4 upon which are mounted a series of cams properly timed for operating the movable parts of the machine. The machine is so organized as to operate upon work presented to it in an oblique pomo aa upon an obliquely disposed spindle sition, this being the most convenient arrangement for the operator.

In presenting the work to the machine the upper is folded and its sides placed upon the opposite surfaces of stationary guide plate 8 set in the machine frame and beveled at its outer edge to facilitate presentation of the work. In order to hold the work in position upon the guide plate 8 before the machine is started and between the feeding steps a pair of clamps or presser feet 10 and 12 are provided. The upper presserfoot 10 is pivotallymounted upon a spindle 22 and the lower presser foot 12 is similarly mounted upon a spindle 24 and provided with a rearwardly extending arm M which carries a cam roller 16 arranged to run upon the cam 6 on the cam shaft 4. The presser feet are provided with interloking arms 13 by which the movement imparted to the'lower presser foot 12 by the cam 6 is imparted in an equal and opposite sense to the upper presser foot 10. The lower presser f00t12 has a downwardly extending arm 18 which stands in v the path ofa treadle actuated bell crank lever 20, by the operation of which the presser feet may be moved away from the guide plate 8 to permit the insertion of the two sides of an upper. H

Two feed frames 26 and 28 are pivotally 30 setin a portion of the machine frame.

Thejfeed frame 26 has a forwardly extending arm in which is slidably mounted a hook setting die or plunger %6 shaped at its lower end to fit the head of a hook. A plate 32 is secured to the lower side of the arm of the frame 26 in which the plunger -16 is mounted and in this plate is located an up setting die 42.

The feed frame 28 has an outwardly extending arm in which is mounted the lower hook setting die or plunger e8. Secured to a the arm of the frame 28 in which is mounted the plunger 18 is a die plate 34 which is shorter than the die plate 32 above men tioned and arranged to be moved in a slot or recess cut in the lower surface of the plate 32. An upsetting die 44 is mounted on the lower side of the plate 3%. The arm of the frame 26 in which is mounted the upper plunger 46 is longer than the corresponding arm of the frame 28 so that the two oppositely disposed hook setting dies or plungers 16 and 48 are maintained out of line with head of the plunger in the setting operation and with an overhanging shoulder which serves to retract the plunger by engaging its flange at the conclusion of this operation. The hammers have arms 51 provided with intermeshing teeth and the lower hammer 52 has also a rearwardly extending arm 54 carrying a cam roller by which the hammers are operated from a cam on the shaft 4:.

A pair of anvils 36 and 38 areprovided for holding the hooks during the setting operation. Each anvil has a flange or lip shaped to enter the opening of the hook and an outwardly extending shank 37 and 39 en circled by a spring tending normally to hold the anvil outwardly away from the upsetting dies. The anvils are mounted to slide freely in the outer ends of a pair of stationary arms 7 6 and 78 which extend outwardly from the machineframe adjacent respectively to the plunger carrying arms of the feed frames 26 and In the setting operation the anvils are forced inwardly with the hooks by the action of the plungers as and 18, as suggested in Fig. i. As soon as the clenched hooks are disengaged from the anvils the latter are immediately moved outwardly and restored to their n'nitial positions by the springs which encircle their shanks.

A hopper 56 is mounted in the machine frame and provided with a'pair of racew ays 58 and 60 by which hooksare supplied to the hook holding flanges of the anvils 38 and 36, the flanges of which are normally maintained opposite the raceway ends. Hook transferring means may be provided if necessary or the hooks may be supplied by gravity. Such transferring mechanism, if

employed may be similar to that shown in my co-pending application above identified and is omitted from the present drawings to avoid confusion.

The setting operation is elected by the simultaneous inward movement of the two hooks by their setting plungers 46 and 48 under the actuation of the hammers 50 and 52. This takes place after a hook has been supplied to the flange of each anvil 36 and 38, it being understood that the barrels of the hooks are disposed in opposite directions and in alinement with the respective upsetting dies 4.2 and 4 1.

At the conclusion of the setting operation the work is fed by the lateral movement of the frames 26 and 28 about the axis of the spindle 30. In this operation the hammers 50 and 52 remain in their inner positions thus-holding the plungers 4:6 and 48 in contact with the heads of the clenched hooks and the hooks against the upsettin dies. The elongated flanges of the pieces 51 and 53, as shown in Fig. 2, permit the feeding movement of the plungers to take place without disengagement from the hammers.

The feed frame 26 is. provided with a lower arm 27 to which is pivoted a link 62 connected at its outer end to a feed link 64 and a spacing lever 66. The link 64 in turn is connected to the lower end of an oscillatory cam lever 68 operated by a cam on the cam shaft 4. The frame 28 is provided with a lower arm 29 disposed beneath the arm 27 above referred to and pivotally connected to a link 70. The link 70 is slightly longer than the link 62 and connected to the arm 29 at a point nearer the axis of the spindle 30 than the point at which the link 62 is connected to the arm 27 of the frame 26. The link 70 is also connected to the feed link 64 and the spacing lever 66 so that its outer end is moved equally and simultaneously with the outer end of the link 62. The angular motion imparted through the link 70 to the feed frame 28 is slightly greater than the angular motion imparted to the feed frame 26 but, on account of the fact that the setting instrumentalities of the frame 28 are located nearer to-their axis of movement than the setting instrumentalities of the frame 26, the actual linear movement imparted to the two pairs of setting devices is equalized and both sides of the upper are fed the same distance in each feeding step.

From the foregoing description it will be apparent that each of the feed frames is pivoted for independent movement about the spindle 30 and that the shorter frame is moved the greater angular amount. By swinging the spacing lever 66 the extent of the feed may be regulated without varying the ratio of the angular movements of the two feed frames.

In using the machine herein disclosed for setting lacing hooks in the uppers of boots, the upper is first folded so that its lower quarter projects beyond the edge of the uppermost quarter, as indicated in Fig. 3. The presser feet 10 and 12 are then opened and the edges of the upper inserted upon opposite sides of the work plate 8. The position of the edge of one quarter is cletermined by the edge gage 72 and of the other by the edge gage 74c. The presser feet are then released and allowed to clamp the sides of the upper in place and the machine is set in operation. The setting plungers l6 and 4.8 are immediately advanced and the hooks, which have previously been supplied to the anvil, are forced through the sides of the upper and have their ends clenched by the upsetting dies 42 and 44:. The feeding operation is then effected by the lateral movement of the two feed frames and during this time the clenched hooks are carried off of the anvils. The presser feet, which are retracted automatically during the feeding operation, are operated to engage the work again at the conclusion of the feeding operation.
